SiSiB® PC2520 3-Ureidopropyltriethoxysilane
SiSiB® PC2520 is a bifunctional organosilane having a reactive organic ureido group and a hydrolyzable inorganic triethoxysilyl group.
The dual nature of its reactivity allows SiSiB® PC2520 to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), functioning as an adhesion promoter and as a silane surface modifier. SiSiB® PC2520 is a 100% 3 ureidopropyltriethoxysilane. It is a 50% solution of silane in methanol.
Application
SiSiB® PC2520 can be used with such polymers as epoxy, phenolic, furan and melamine resins, polyurethanes, PA, PBT, PE, EVA, PP, PVB, PVAC, acrylics and silicones.
SiSiB® PC2520 can be used as a size constituent of finish for glass fiber/glasssilicone fabriccomposites.
SiSiB® PC2520 can be used as an additive to phenolic, furan and melamine resins for foundry resins and abrasives.
SiSiB® PC2520 can be used as an additive for sealants and adhesives.
SiSiB® PC2520 can be used as ansilicone additiveand/or primer for paints and varnishes to improve adhesion to the substrate.
The most important effects which can be achieved using PC2521 are improvements in product properties, such as:
Improved mechanical properties: e.g. flexural strength, tensile strength, impact strength, modulus of elasticity.
Improved resistance to moisture and corrosion.
Higher temperature of deflection under load.
Packing and Storage
SiSiB® PC2520 is usually supplied in 50% methanol solution. SiSiB® PC2521 is supplied in 180Kg steel drum.
In the unopened original container SiSiB® PC2520 has a shelf life of one year in a dry and cool place.
